I am coming up on my one-year anniversary with my M1 Max 14-inch MacBook Pro. It is the best computer I have ever used. It is so fast and a powerhouse in every way. I use it for Xcode, Final Cut Pro, music production, and it always delivers.

However, computers are not without little hiccups here and there. Lately, I have had some battery issues when it is asleep. I am sure there is some little app that has been preventing my MacBook Pro from sleeping. When I have reached into my bag to get it out, it has been noticeably warm and the battery is depleting when it should be asleep. In all fairness to the computer, I do run a lot of apps and my menu bar is embarrassingly filled with running applications.¹

I am still not certain which process has been causing the heat and battery issues, but I did recently find an interim solution. With a short shell script and Keyboard Maestro, I can quickly disable WiFi before I close the lid. This has immediately brought back amazing battery life and my computer is super cool when I pull it out of my bag.

The script for toggling WiFi in the Terminal is:

networksetup -getairportpower en0 | grep "On" && networksetup -setairportpower en0 off || networksetup -setairportpower en0 on

I setup a Keyboard Maestro hotkey to quickly toggle the WiFi on and off.

I love the Mac.
